ABSTRACT:
A head rest and restraint assembly has, as its principal component, a padded, shaped arm which has one end thereof contained in a mounting member. The contained end has a splined portion thereon which is adapted to mate with an interior splined portion of the mounting member, which comprises a hollow cylinder. Adjustment of the angular arm is accomplished by pushing the end of the arm into the cylinder against the force of a coil sprint until the splines dis-engage, allowing rotation of the arm, when the arm is released, the spring forces the splines into re-engagement, thereby fixing the angular orientation of the arm. Pairs of arms mounted in brackets, for example, can be used with existing vehicular headrests, or a replacement or new head rest may be formed with bores to accept and hold the mounting means.
